+On the Anthropic-compatible streaming path, OpenClaw now disables MiniMax
+thinking by default unless you explicitly set `thinking` yourself. MiniMax's
+streaming endpoint emits `reasoning_content` in OpenAI-style delta chunks

+into visible output if left enabled implicitly.

 ### MiniMax M2.7 as fallback (example)
 
 **Best for:** keep your strongest latest-generation model as primary, fail over to MiniMax M2.7.
